The Squid HTTP Proxy team is very pleased to announce the
availability of the Squid-5.8 release!

This release is a bug fix release resolving several issues
found in the prior Squid-5 releases.

The major changes to be aware of:

 * Bug 5162: mgr:index URL do not produce MGR_INDEX template

This bug shows up as Squid producing just the text "mgr_index" instead of the intended template contents when the cache manager API is requested. Breaking the use of third-party cache management tools and also cachemgr.cgi auto-detection of support for those tools.

 * Bug 5241: Block all non-localhost requests by default

This release changes the default squid.conf to disable the rule:
  http_access allow localnet

This change affects new Squid installs only.

 * Bug 5241: Block to-localhost, to-link-local requests by default

This release adds a predefined ACL named "to_linklocal" which matches traffic attempting to access link-local network services. Such traffic can be a problem for proxy operating within Cloud services or container hosting.

Squid installations which have enabled:
http_access deny to_localhost

May wish to also enable:
  http_access deny to_linklocal

  All users of Squid-5 are encouraged to upgrade as soon as

  Users of Squid-4 holding back due to earlier release issues
  are encouraged to test this version for upgrade.

See the ChangeLog for the full list of changes in this and
earlier releases.
